Notes for using Hyper-V
System halt Time when Duplexing CPU Module
In the synchronization process of CPU modules, a memory copy is performed
to duplex memory on both CPU modules. Some part of memory area can be
copied without stopping the system while the other part requires the system to
stop. When using Hyper-V, the system cannot use the function to copy without
stopping the system. Therefore, the system does not respond for a longer
period of time during the synchronization process of CPU modules as
compared to when Hyper-V is not used. The following are the reference
values of each model.
Note:
1)Memory copy time depends on the memory size installed in the system.
2) When a large amount of memory is installed, non-responding time will be
longer and the connection from a client may time out. Adjust the timeout
values of TCP/IP, etc., on the client side as necessary.
* Actual time may differ depending on the status of use.
